Abstract (en)
[origin: US2013059105A1] Methods for producing an at least partially cured layer by applying a layer including a (meth)acrylate-functional siloxane to a surface of a substrate, and irradiating the layer in a substantially inert atmosphere with a short wavelength polychromatic ultraviolet light source having a peak intensity at a wavelength of from about 160 nanometers to about 240 nanometers to at least partially cure the layer. Optionally, the layer is at a curing temperature greater than 25° C. In some embodiments, the layer has a thickness of about 0.1 micrometers to about 1 micrometer. In certain embodiments, the layer is substantially free of a photoinitiator and/or an organic solvent. In some particular embodiments, irradiating the layer with a short wavelength polychromatic ultraviolet light source takes place in an inert atmosphere including no greater than 50 ppm oxygen. The substantially cured layer may be a release layer or a low adhesion backsize (LAB).
